  • the invention relates to a centrifugal spreader according to the preamble of Claim 1.
  • centrifugal spreader is, for example, in DE-OS 18 01 180 described.
  • This centrifugal spreader has a funnel-shaped storage container on, in the lower region of which an outlet opening is arranged.
  • the outlet opening is in an upright wall.
  • the storage container is with completed a base plate.
  • stirrer arranged which is approximately parallel to the base plate aligned stirring element, which at the outer end down is bent and forms an attachment element. This approach element covers the Outlet opening.
  • Such a stirring element is not for one Centrifugal fertilizer spreader suitable, in which the outlet opening in the base plate is arranged. Furthermore, in this known centrifugal spreader considerable disadvantage that another stirring element, which is used as a scraper element acts, is arranged at a very short distance from the base plate. Hereby the start element is very large because of the distance between the bottom of this Stirring element and the base plate smaller than the grain diameter of the material to be deployed.
  • the invention has for its object a stirrer for one To create centrifugal fertilizer spreader, which has a low start-up and Has drive torque and at the same time ensures that only a small Remaining amount remains in the storage container.
  • the scraper element can be designed to be inherently elastic. However, it is also possible that the scraper element by an at least approximately parallel to the Bottom plate extending pivot axis is pivotally attached to the stirring element.
  • a simple arrangement for the scraper element can be achieved in that the stirring element seen in front view U-shaped, with the free legs facing downward, is formed. Thus, at the free ends of the the scraper element projecting below the pivoting element.
  • stirring element is eccentric on the drive shaft is attached. This can be achieved that the scraper element after internally directed conveying effect on the material to be applied. This is an advantage if the outlet opening only opens over a small cross-section becomes. Due to the spreading technology of centrifugal fertilizer spreaders, the Opening of this discharge opening in the inner area of the base plate.
  • the scraper element in the Seen from above is U-shaped.
  • the scraper web is at least partially aligned approximately parallel to the base plate.
  • the scraper element strives to cover the entire surface of the To lay the base plate on.
  • the remaining layer in the storage container can be left at layer height according to the grain size or even lower values reduce.
  • the shorter end opposite the longer stirring element of the stirring element in connection with the extension of the scraper element designed such that the extension of the scraper element over the web of Stirrer protrudes beyond the smallest opening cross-section, that is Beginning sweeps when opening the outlet.
  • This will, on the one hand a very smooth and even outflow of the material through the outlet opening reached to the centrifugal disc located below the outlet opening, on the other hand, the outlet opening becomes blocked by clods prevented by being crushed by this element.
  • the base plate in which the outlet opening is arranged can be completely flat, however, also be arched.
  • the course of the scraper edge of the scraper element is based on the contour of the Base plate adapted. This ensures optimal residual emptying reached.
  • the centrifugal fertilizer spreader has the frame 1 and the storage container 2. On the frame 1 and the reservoir 2 are in known and therefore not shown way on the front three-point coupling elements for attachment of the centrifugal fertilizer spreader to the three-point linkage of a tractor arranged.
  • the reservoir 2 is through the roof-shaped middle part 3 in the two Outlet funnel 4 divided.
  • the outlet funnels 4 are on their underside closed the bottom plate 6 having an outlet opening 5.
  • the Opening width of the outlet opening 5 is set by the slide 7.
  • a rotating driven centrifugal disc 8 with the throwing blades 9 is arranged.
  • the throwing blades 9 are known and not shown Swiveling in the angular plane on the centrifugal disks 8 in different angular positions adjustable.
  • the Centrifugal disks 8 are light on the drive shafts 10 of the angular gear 11 arranged detachably, so that they can be easily constructed against other trained Centrifugal discs with throwing blades for other working width areas are interchangeable.
  • the centrifugal disks 8 are driven by the angular gear 11 and the shaft train 12 driven by the central transmission 13.
  • the middle gear 13 has the input shaft 14, which is connected to the PTO shaft by means of a cardan shaft of the tractor carrying the fertilizer spreader is connected.
  • the waves 15 of the wave train 12 are telescopic so that the Gear 11 with the centrifugal disks 8 transversely to the direction of travel 16 in different positions to the metering device 7 are adjustable.
  • the slots 17 arranged so that the gear 11 with the Centrifugal disks 8 are displaceable in the arrow directions 18 and 18 '.
  • the outlet funnels 4 and 5 is above the bottom plate 6 and Dosing device 7 arranged the slowly moving agitator 20.
  • To the The drive of the agitator 20 is a drive shaft running transversely to the direction of travel 21 arranged protruding into the reservoir 2.
  • At the ends of the Drive shaft 21 is arranged an angular gear 22.
  • the upright and after below projecting shafts 23 of the bevel gear 22 carry the agitator 24.
  • Die Drive shaft 21 is to be driven by drive shaft 15 via a chain drive 25.
  • the stirring element 24 has the U-shaped stirring element 26 with the horizontal web 27 and the free downward legs 28 and 29 on.
  • the U-shaped scraper element 30 In the area of the free ends of the legs 28 and 29 is the U-shaped scraper element 30 by means of the pivot pin 31 and 32 through bores 33 which are arranged in the legs 28 and 29, is pivotally mounted.
  • the scraper element 30 has the scraper web 34, which is aligned or at least partially approximately parallel to the base plate 6 the shape of the base plate 6 is adapted.
  • the scraper element 30 has the round cross section shown in Figure 4.
  • the outer leg 28 of the Stirring element 26 is employed in such a way that its front 35 has a larger one Distance as its rear side 36 to the axis of rotation 37 of the agitator 24, referred to the direction of rotation 38.
  • this leg 28 is on the handle set so that it has an inward promoting effect on the applies material to be spread and the material inwards towards the Opening of the outlet opening 5 pulls. Furthermore, the scraper web 34 is of this type trained that he also has an inward promoting effect on the material to be deployed.
  • the stirring element 26 is at a distance of at least 2cm, preferably from 3-6cm to the base plate 6.
  • scraper element 30 can also a scraper element, with the cross sections 39 or 40 corresponding to the Fig.5 and 6 may be provided.
  • the scraper web 34 has seen in relation to the direction of rotation 38, a front lower region 41 on the runs upright.
  • a rubber or plastic layer 42 or Plate attached so that a good residual emptying is possible.
  • the operation of the agitator is 24 as follows:
  • the stirrer 24 rotates in the direction of the arrow 38 via the drive shaft 23 driven. When starting up, this initially lifts up on the base plate 6 overlying scraper element 30 and adjusts itself to a height which is about Height of the linkage 33 is. When the reservoir 2 empties and only there is still a small amount of material in the storage container 2, this drops Scraper element 30 downwards and the scraper web 34 strives on the Base plate 6 to lie on. Thus, the scraper element 30 promotes that on the Base plate 6 lying material through the open outlet opening 5 to the Centrifugal disc 8, so that only a very small amount remains in the Reservoir 2 remains.
  • the lower region 43 of the Storage container 2 has a cup-shaped shape with approximately upright walls 44 on.
  • the diameter of this lower area 43 is the outer Adjusted orbit of the agitator 24.
  • the stirring element 45 according to FIG. 8 differs from the stirring element 24 of FIG. 2 to 7 in that the leg 46 is not inclined.
  • the stirring element 47 according to FIG. 9 differs from the stirring element 24 of FIG. 2 to 8 in that on the scraper element 48 a standing on handle Conveying element 49 is arranged, which corresponds to the leg 28 of the Stirring element 24 according to Figure 2, the material from the outer area to the inside promotes.
  • the stirring element 50 according to FIG. 10 differs from the stirring element 24 according to 2 and 3 in that the scraper element 51 from two in one blunt There are webs 52 and 53 lying at an angle to one another, which in turn have Hinge pins 31 and 32 on the upright legs 28 and 29 of the Stirring element 26 are pivotally attached.
